Psoriatic arthritis is an inflammatory arthritis that affects 1 in 400 Canadians and can lead to significant joint damage and disability. Despite the availability of effective medications, many patients continue to experience debilitating joint pain and stiffness that have significant impact on their quality of life.

Patients with psoriatic arthritis often seek information about diets to assist with improving their symptoms. However, little is known about the effect of different diets on disease activity in psoriatic arthritis. To help answer this question, Dr Lihi Eder, rheumatologist and scientist at Women’s College Hospital and the University of Toronto, and her collaborators from the University of Pennsylvania and New York University, have launched a clinical trial to investigate if dietary modifications can improve symptoms of psoriatic arthritis.


Dr. Eder and her team are looking for research participants with psoriatic arthritis who are willing to modify their diet for six months – following a consultation from a dietitian – to examine the effects of dietary changes.

You may be eligible to participate in the clinical trial if you are:

  • Age 18 to 80 years
  • Have been diagnosed with psoriatic arthritis by a rheumatologist
  • On stable treatment for psoriatic arthritis for the past three months
  • Willing to modify your diet for six months

* Please note additional criteria may apply.
